Inodorus

Inodorus is a Latin adjective used in biological nomenclature. It is not the name of a genus or a standalone taxon. Instead, inodorus appears as an epithet or descriptive element in the binomial names of various species across different families and kingdoms. The epithet signals a trait noted by the describing author, most commonly the absence of a discernible odor in parts such as flowers, fruits, leaves, or tissues. Because epithets are not unique to a single lineage, multiple, unrelated species may bear the same epithet in their scientific name.

Etymology and meaning: The term derives from Latin in- meaning 'not' and odorus meaning 'having a smell' or 'having a scent,' effectively 'odorless.' In taxonomic practice, the same adjective can be employed independently in different taxa to describe similar traits, so its precise referent is context-dependent. Changes in spelling or gender agreement may occur to match the genus name (e.g., inodorus, inodora, inodorum).

Taxonomic usage and interpretation: Because 'inodorus' is an epithet rather than a taxon, there is no single organism known as 'Inodorus.' Instead, multiple species in different genera may include 'inodorus' in their binomial names, such that the term describes a lack of odor rather than a specific lineage. Researchers examining a name containing 'inodorus' should consult the full binomial and the original species description to understand the trait emphasized by the author. The term illustrates how Latin descriptors contribute to the descriptive richness of scientific names.
